Ingredients for Long John Silvers Tartar Sauce

These nine carefully balanced ingredients recreate the signature Long John Silver’s tartar sauce with restaurant-quality precision.

Ingredient Amount Notes
Mayonnaise 🥫 1 ½ cups Full-fat for creamy texture
Dill Pickles 🥒 ½ cup Finely chopped, juice reserved
White Onion 🧅 2 tbsp Finely minced for sharpness
Fresh Lemon Juice 🍋 2 tbsp Newly squeezed for brightness
Dijon Mustard 🟡 1 tbsp Smooth, not grainy variety
Granulated Sugar 🍚 1 tbsp Balances tangy elements
Dried Dill Weed 🌿 1 tsp Crushed between fingers
Worcestershire Sauce 🫒 ½ tsp Anchovy-free if preferred
Hot Sauce 🌶️ ¼ tsp Optional for subtle heat
Salt 🧂 ½ tsp Fine sea salt preferred

The mayonnaise base is critical for authentic texture. **Duke’s or Hellmann’s** provide the ideal richness and body that commercial brands achieve. Opt for full-fat versions—low-fat alternatives compromise the sauce’s ability to cling properly to fried seafood. Fresh lemon juice (not bottled) delivers the necessary brightness, while **Heinz dill pickles** offer consistent tang and crunch. For professional results, measure ingredients precisely using weight for the pickles (2.5 oz finely chopped) if volume measurements prove inconsistent.

For dietary adaptations, **vegan mayonnaise (Just Mayo or Hellmann’s Vegan)** substitutes seamlessly at a 1:1 ratio. Omit Worcestershire sauce or use **Annie’s Vegan Worcestershire** to maintain pescatarian standards. The hot sauce can be adjusted—**Tabasco** for classic heat or **Cholula** for milder flavor. Sugar alternatives like **organic cane sugar** work identically, though liquid sweeteners (agave, honey) will alter the sauce’s viscosity and should be avoided.

Store completed tartar sauce in an airtight container with plastic wrap pressed directly against the surface to prevent oxidation. Maintains optimal quality for **7 days refrigerated**; do not freeze as separation will occur. For restaurant-style presentation, transfer to a squeeze bottle and refrigerate 2 hours before serving to allow flavors to meld completely. The sauce’s consistency will thicken slightly upon chilling.

Why You’ll Love This Recipe

  • No Food Processor Needed: I just grab a knife and cutting board—the only chopping is half a white onion and a couple dill pickles. Honestly, it’s faster than dragging out appliances for something that comes together in 5 minutes with a mixing bowl.
  • That Tangy Crunch: The lemon juice brightens up the mayo while the pickles and onion add this *perfect* bite—like the sauce you’d sneak extra packets of, but better. Between us, I’ve caught my husband eating it straight with a spoon.
  • Fish Fry’s Best Friend: Slather it on crispy cod, drizzle over shrimp tacos, or (my weird flex) dip fries in it. I’ll be real: this batch lasts me through two seafood dinners *and* a sad desk lunch with leftover fish sticks.
  • Stays Good for Days: Unlike store-bought, this keeps its zing for up to a week in the fridge. I make a double batch Sunday and suddenly, Tuesday’s frozen fish fillets taste like a proper meal. (Yes, even on a Tuesday night.)

Step-by-Step Instructions for Long John Silver’s Tartar Sauce

This method ensures you achieve the signature tangy, creamy balance that makes this sauce perfect for seafood.

Step 1: Prepare the Pickle and Onion Base

Begin by finely chopping the 0.5 cup Dill Pickles until you achieve uniform pieces about 1/8-inch in size. I recommend using a sharp chef’s knife and rocking it through the pickles for consistent results. Transfer the chopped pickles to a medium mixing bowl, including any accumulated juices from the cutting board.

Next, finely mince the 2 tbsp White Onion until it’s nearly translucent. The onion should be cut small enough that it disappears into the sauce rather than providing distinct bites. Add the minced onion to the bowl with the pickles. This combination forms the textural foundation of your sauce.

Step 2: Combine Wet Ingredients

To the pickle-onion mixture, add the 1.5 cups Mayonnaise, 2 tbsp Fresh Lemon Juice, and 0.5 tsp Worcestershire Sauce. Use a silicone spatula to fold these ingredients together until just combined. The mayonnaise should remain smooth with visible flecks of pickle and onion throughout.

Now incorporate the 1 tbsp Dijon Mustard and 0.25 tsp Hot Sauce. The mustard adds depth while the hot sauce provides subtle background heat. Stir for 30 seconds until fully integrated, but avoid overmixing—you want to maintain the sauce’s chunky texture that’s characteristic of the original.

Step 3: Balance Flavors and Season

Sprinkle the 1 tbsp Granulated Sugar evenly over the mixture. The sugar counterbalances the acidity from the lemon juice and pickles. Add the 1 tsp Dried Dill Weed, crushing it between your fingers as you sprinkle to release its aromatic oils.

Finish with the 0.5 tsp Salt and fold everything together for 1 minute until completely homogeneous. The sauce should appear creamy with visible specks of green dill and pale onion. Taste and adjust seasoning if needed, though the measurements provided should yield perfect balance.

Step 4: Rest for Flavor Development

Transfer the completed sauce to an airtight container and refrigerate for at least 2 hours before serving. This resting period allows the flavors to meld completely. The acidity will mellow slightly while the dill and onion flavors infuse throughout the mayonnaise base.

When properly chilled, the sauce will thicken slightly and develop the signature tangy-sweet profile. The color should be pale cream with green and white specks distributed evenly. For best results, prepare this sauce 24 hours in advance to allow maximum flavor development.

Make-Ahead Tips for This Dish

Prep Ahead Strategy

I always make this tartar sauce at least 24 hours before I need it. The flavors develop dramatically during this time, with the dill and onion mellowing into the mayonnaise base. Prepare the complete recipe as directed, then transfer to an airtight container. Press plastic wrap directly against the surface to prevent oxidation before sealing. 💡

For meal prep, I divide the sauce into 8-ounce mason jars—each holds about 1 cup, perfect for family meals. Label with the date using masking tape. The sauce maintains peak quality for 7 days refrigerated, though I’ve found it still tastes great up to 10 days if stored properly.

Quick Assembly Tips

When short on time, I prep the dry ingredients separately. Measure the dried dill, sugar, and salt into a small container, and finely chop the pickles and onion together. Store these components in the fridge for up to 2 days before mixing with wet ingredients.

The mayonnaise base can also be pre-measured into a bowl and covered. When ready to assemble, simply add your prepped dry ingredients and mix. This approach cuts active prep time to just 2 minutes when you’re ready to serve.

Flavor Boosting Trick

Here’s my secret for extra depth: After mixing, let the sauce sit at room temperature for 30 minutes before refrigerating. This brief rest allows the flavors to begin melding. I notice the dill becomes more pronounced and the acidity softens slightly.

For even better results, add 1 tsp of the reserved pickle juice from your chopped pickles. This amplifies the tangy quality that makes Long John Silver’s version so distinctive. Just don’t exceed this amount or the sauce may become too thin.

Portion Control

For entertaining, I use 2-ounce condiment cups with lids to portion individual servings. These stack neatly in the fridge and make it easy to grab exactly what you need. The small portions also prevent waste when serving smaller groups.

When hosting, I set out a main bowl with a serving spoon plus these pre-portioned cups. Guests appreciate having the option for individual servings, especially when enjoying messy fried foods.

Freezing Considerations

While I don’t recommend freezing this sauce (the mayonnaise separates), you can freeze the prepped pickle-onion mixture alone. Portion it into ice cube trays, then transfer frozen cubes to a freezer bag. Each cube equals about 1 tbsp of the mixture.

When ready to use, thaw the cubes overnight in the fridge, then mix with fresh mayonnaise and remaining ingredients. This preserves the fresh flavor while saving prep time on busy days. ❄️

Equipment Prep

Before starting, I gather all tools: a medium mixing bowl, silicone spatula, sharp chef’s knife, and cutting board. Having everything ready makes the process smoother. I also chill my mixing bowl for 10 minutes beforehand to help maintain the sauce’s thickness.

For easy cleanup, I place a damp paper towel under my cutting board to prevent slipping. This small step makes chopping the pickles and onion much safer and more efficient.

Frequently Asked Questions

1

How long does homemade tartar sauce last in the fridge?

When stored in an airtight container, this tartar sauce stays fresh for 7-10 days. For best quality, press plastic wrap directly against the surface before sealing to prevent browning. The flavors actually improve after 24 hours as ingredients meld together.

2

Can I make this sauce without mayonnaise?

For a mayo-free version, substitute with Greek yogurt or sour cream at a 1:1 ratio. The texture will be slightly thinner, so reduce lemon juice by 1 tbsp. Vegan options like cashew cream or silken tofu blends work too, though flavors will differ from the classic version.

3

Why does my sauce taste too sweet or too tangy?

Balance is key! If too sweet, add 1 tsp lemon juice or 0.5 tsp Worcestershire. For excessive tang, mix in 0.5 tsp sugar or 1 tbsp extra mayo. Always adjust gradually and retaste—small changes make big differences in flavor.

4

What’s the best way to chop pickles for authentic texture?

Use a sharp chef’s knife and cut pickles into 1/8-inch dice. For consistency, stack slices and cut lengthwise. Avoid food processors—they create uneven textures. The goal is visible specks, not a uniform puree.

5

Can I use fresh dill instead of dried?

Yes, but use 3x the amount (1 tbsp fresh = 1 tsp dried). Finely chop fresh dill and add it last to preserve its bright flavor. Note that fresh dill may slightly alter the sauce’s color and shelf life.
